With an objective to evaluate the antibacterial activity of triazine derivatives, a series of 2,4,6-trisubstituted- 1,3,5-triazine were synthesized and characterized by FTIR, 1H-NMR, 13C-NMR, mass spectroscopy and elemental analysis. The minimum inhibitory concentration (MIC) of the compounds that displayed favourable zone of inhibition was determined by broth microdilution method. Derivatives with morpholinyl substituent (4a and 4i) demonstrated good in vitro activities against Gram-positive organisms, whereas two of the compound bearing a diethylamino side chain exhibited moderate (4e) to broad spectrum (4j) activity comparable to streptomycin. The promising activity of the latter maybe attributed to the substitution of electron releasing group at para position of phenyl rings.
为了评估三嗪衍生物的抗菌活性,合成并表征了一系列2,4,6-三取代-1,3,5-三嗪化合物,包括FTIR、1H-NMR、13C-NMR、质谱和元素分析。通过肉汤微量稀释法测定了显示出良好抑制圈的化合物的最小抑制浓度(MIC)。具有吗啉基取代基的衍生物(4a和4i)对革兰氏阳性菌显示出良好的体外活性,而具有二乙氨基侧链的两个化合物显示出中等(4e)至广谱(4j)活性,可与链霉素相媲美。后者的潜在活性可能归因于苯环对位上电子给体基团的取代。
